Description
Skyworks family of sampling phase detectors, SPD1101-111,
SPD1102-111 and SPD1103-111, consists of a step recovery
diode (SRD), a series pair of Schottky mixer diodes and a pair
of coupling capacitors. These chip on board components are
manufactured using automated pick-and-place techniques to
provide uniformly performing, surface mountable, small foot-
print devices with excellent high-frequency performance.
Sampling phase detectors are typically used in systems which
lock the output signal of a high-frequency voltage controlled
oscillator (VCO) to a lower frequency, stable reference oscillator
output signal. The reference oscillator signal is applied to the
SRD, which produces outputs at the harmonics of the reference
oscillator frequency. This comb of harmonics is coupled to the
Schottky series pair, which comprises a singly balanced mixer,
via the on-board coupling capacitors. The high-frequency signal
from the VCO is applied to the center node of the Schottky
diode pair. The high-frequency VCO signal is mixed with the
harmonics of the low-frequency, stable reference oscillator
signal in the Schottky diode pair. The desired output signal,
which is typically the different frequency signal that is produced
by the VCO signal and the harmonic of the reference oscillator
signal nearest to it in frequency, is present at pin 4 of the
sampling phase detector, along with the other mixer products
produced by the other harmonics of the reference oscillator
signal and the VCO signal, all of which are higher in frequency
than the desired output signal. The desired output signal is
selected by an external low pass filter, and can be utilized to
lock the frequency and the phase of the VCO signal to the
stable reference oscillator signal.

Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
CAUTION:
Although this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
